This spring bears against a.bracket' 75 se cured to the frame member 57 as shown, particularly inFigure 4;

The frame member 46 has a central Vlongitudinal groove 76 provided, ineach end wall,

with bores 77. See Figures 8 and 9. In each of these bores is mounted aspring pressed plunger 78 having a head 79 at itsrinner'end p mountedfor movement within the recess 76. p Interposed between the heads 7 9 soas lto be normally centered thereby withinfthe recess 7 6 is a slide 80in which is journaled av sleeve j 81fhaving oppositely disposed'bev'eledgears 82 and 83 at the respective ends thereof..

A sleeve 95 is adj ustably mounted on the bar91 and adapted to be held in any desired position relative thereto bya'set sfcrew 96 or the like. See Figure 13. Sleeve 95 is slidablymounted on guidev pin 97 extending from guide 94 andA a spring 98ismounted on this pm and servies to hold the foot 92 of the`shifftingybar 9 1 normally pressed against arm86 as shown` in Figure 8and --Figure 10.

The frame l member provided with a longitudinal' groove 99 opening atonel end into the recess- 7 6 and through that side of the 'frame membernearest the compression chamber.' In this groove is mounted' a couplingslide 100 the inner end of which is adapted to work across 'the path ofthe bolt 488 and has an opening 101 designed to receive the bolt 88 whenbrought to positionin alinement therewith. This coupling slide is heldin the groove by any suitable means, such as a retaining plate 102 andpivotally connected tothe outer end of the coupling slide are oppositelyextended levers 103. As shown ulled away fromF frame v particularly inFigure 9 one of these levers y is provided with a notch 104 in that endthereof nearest its ivot 105. The other lever has a bo 106 sli ablymounted therein 'and provide with a 'spring 107. This spring controlledbolt isso located that whenthe two' levers are brought into substantialalinement, the bolt will be automatically projected into the notch 104,thereby holding' the levers a ainst independent movement about the.

' 1vot 105.\ The outer end of the bolt 106 s an arm 108 adjustablyconnected thereto mounted on the Guide rods 56 This'crossA head has aninterlorly screw threaded sleeve 116 fixedly mounted .in the centerportion thereof through which the screw 71 extends. Thus as this screwis rotatedl the cross head 115 will be fed along the guide rods 56toward or from the frame member 48. In Figure 4 the cross head has beenshown by broken lines in normal position and, by full lines, in itsother extreme position.

Secured to-the cross head 115 adjacent each end is a stud 117 on which adisk 118 is mounted to rotate freely. A boss 119-is preferably formed onthe cross head 115 so that the stud 117 can be extended through thecenter thereof and this boss constitutes a thrust bearing for the disk.Screw threa'ded recesses 120 are formed in the disk 118 at diametricallyopposed points and seated in each of theserecesses 1s the screw threadedend of a tubular needle housing 121. These housings are parallel and areof such length that, when the cross head 115 is in the positionindicated by full lines in Figure 4, they will extend ytransverselythrough the body structure of the press and beyond the far side thereof.For the purposeof'maintainingthese tubular needle housin s in properpositionsv relativel to each other, t e two needle housings extendedfrom each disk 118 are slidably mounted within connected disks 122rotatably mounted on the frame member 46. These disks con `stituteclosures for openings 123 formed in the frame member 46 and when eah airof needle housings 121 is rotated about t e stud 117 with diskv118, thedisks 122 will also be rotated therewith about the central axis thereof.1 p v The tubular needle housings 121 of each pair are connected nearthe disk 118 b clamping strips 124 which bind upon sai tubular housing,a bolt 125 being used for drawing them toward each other. This bolt alsoconstitutes the pivot of opposed crossed levers 126. Each lever has alon arm and a short arm. The long arm is o set atan angle to provide afinger 127 and these fingers pro- )ect into short longitudinal slots1,28 formed in the respective tubular housings 121 close to the disk118. The short arms of the two levers cooperate to forma small V-shapedrecess 129 when the leversare in their normal positions as shown inFigure Secured to the centers of the disks 122 through which Ithe pairof tubular housings isilextended, is a conin Figure 7, thereby swingingthe fingers 127 within the slots 128 substantially inthe direction ofthe len h of the housings 121.

The free en of each needle housing has an arcuate extension 132 whichcan be formed by cutting away a part of the end of the housing throughapproximately 180. A cross meur ber 133 is secured in the tubularhousing near this pro'ecting portion or guide and shdabl mounted thereinis a rod 134 one end of whic is secured'to a needle 136 in the form of arod slidable in the tubular housing 121. To thev y other end of the rod134 is secured a disk 137 constituting a'jaw, this disk being preferablyY formed with' teeth or serrations 138 in that face thereof nearest theneedle. A spring 139 is located in the housing 121 and thrusts at oneend agains the cross member 133 and at its other end against the needle136. Thus th'e needle is held normally pressed back to the positionshown in Fi ure 6 and jaw 137 is normally positioned at t e inner end ofthe guide extension 132 and within the tubular housin 121 close to theterminal shoulder 140 locate lat the inner endA of the 'guide extension132.

coupling levers 141. Each ofthese levers extends through a slot 142 inthe frame member 46 and is connected to said frame member by aYV finger143 mounted in an ear 144 located at one end ofthe slot and extendedfrom the frame vmember 46 toward the press body 40. When the lever 141is in one extreme position'it' bears a inst one end wall of the slot 142as shown 1n Figure 11 and extends at ri ht angles fromv frame member 46into the si e portion of the baling press bod 40. The other end of lever141 has a tapere head 145 adapted to be engaged and held by a latch 146p1v'l o tally mountedon one side of the yoke 85. A finger 147 isextended from one end of the latch and is en aged by one end' of acoiled spring 48 the ot er end of which is connected to a finger 149extending from lever 141 close nol to the head 145. Latch 146 has a Wing150 extending from the head thereof and supported close to the crosshead 87. This Wing has a shoulder 151 adapted, when the .head of thelatch 146 is in its innermost position, to engage back of the cross head87 and hold it and the arm 86 against sliding movement under the actionot' the spring pressed plungers 78. This position of the parts is onlypossible when the-'latch 146 is out of engagement with the head 145 oflever 141 as shown in-Figure 10. At this time lever 141 is held againstmovement by the presure thereagainst of compressed hay or the likeexposed through the open side of the body 40 ofV the baling press. Thismaterial under compression has been indicated generally1 at '152 inFigure 10.

Extending from the fra-me member 46 `adjacent the levers 103 are wings153 each of Wlhich has a guide slot 154. A yoke 155 is slida l latdrallyextending bolts 156 extending through the slots 154 so that the yoke canbe slid longitudinally of the slots Without swingf ing relative to thewings. One of the bolts extending through each wing carries a roller157, this roller being reinforced by a bracket 58 'mounted on both of`the bolts 156, as shown in Figure 14. Rods 159 'are fastened to thebase portions 160 of the wings and are slidably engaged by theintermediate portion of the yoke 155. Springs 161 are mounted on theserods and serve to hold the yoke 155 normally pressed yielding away fromthe bases 160 of the wings. Carried by the yoke between the rods 159 isa block 162 having a stem 163 fastened in the yoke. The rollers 157 areso located that when the levers 141 are thrust to the positionsillustrated in Figure 10 by pressure of compressed material 152thereagainst, the fingers 149 will bear against said rollers 157 andslide the yoke 155 toward the frame member 46 against the action of thesprings 161. f

Journaled at one side of the baling press is' a drive shaft164 connectedby a universal joint 165 to a square shaft 166 which extends through theyoke 155 between the springs 161, through an opening 167 in theA arm 86and through the sleeve 81. This sleeve is adapted to rotate with theshaft 166. It will be noted that thecrosshead 87 is out away at 167 (seeFig. 12) to'permit rotation thereof and thus it will be seen that whilethe shaft 166 isextend- Ved Athrough the mechanism carried by thel framemember 46, it can rotate freely therein, operating solely the sleeve 81and the parts controlled thereby. A short worm 168 isse- 1 cured to theshaft 166 4at a point adjacent the mounted between these wings andhasengage.

For the purpose of holding the frame member 46 and the parts associatedtherewith normally positioned'as in Figure 1 cables 169 are attached tothe outer ends of the respective levers 103 and are guided over sheaves170. These cables are securely fastened at one end as snown'at 171 andprovide depending loops 17 2 which support movable weights 173. TheseWeights are sutliciently heavy to pull through the cable 169 upon theframe member 46 so as to cause it to travel from the position shown forexample in Figure 3 to the position shown in Figure 1.

Cooperating with the mechanism thus far described'is a dividing block174 adapted to be placed within the baling press/for the purpose ofseparating adjacent bales in the process of formation; "One of theseblocks is to be 4 placed in the machine after the material' of each balehas been compressed to produce a bale of the desired size. Each block is-provided with slots arranged in pairs, the slots of each pair beingprovided for each pair of. needles. The slots, which have been indicatedat 175, are extended into opposed faces lof the block and throughout thelength ofthe bloc-k from one side to the other. The innermost port-ionof each of the slotsissubstantially cylindrical as shown at 176 so thatthe Itubular housings 1,21 of the needles can be received thereby.4Obviously these slots are located where the needles can be movedthereinto after the block 174 has been properly coupled to the framemember 46. A recess 177 is formed in one side of the block near eachpair of slots 175 and is vlocated where it will receive one of thelevers 141 when the block is brought to proper position relativethereto.

Rollers 178 are mounted on the wall 41 adjacent the worm 168 for'engagement by the levers 103 as shown in' Figure 1.

Normally' the various parts of the apparatus are located as in Figure 1.At this time tlie levers 103 are locked in alinement. They are incontact with the rollers 178 against which they have been pulled by theweightedcables 169. After coming into contact with the rollers, thelevers 103 lwhich normally diverge ,toward the rollers 178 while beingpulled by the cables are straightened out because the worm 168 engagesthe depressed block 162 and pulls the frame member. 46 toward the wall41. strain the outer ends of the levers 103, the inner ends of thelevers will be advanced as the frame member 46 is pulled by the lshortworm 168. As the block 16:2 passes oif of v theend of the worm the twolevers are brought into alinement and are'locked against relativemovement by the spring actuated bolt 106`V` Obviously at this time lever141 is arranged as'shown in Figure 10, the pressure of the compressedmaterial at the open side of the body 40 being such as to cause finger149 to maintainlthe yoke 155 and block 162 pressed As the rollers 17 8re-V 55 the 'the thrust against the 'levers 141 and push the shown) andforced longitudinally ofthe machine. As this block comes to 'positionbeside the frame member 46, the two levers 141 will pass ofi' of thecompressed material and be free to swing inwardly into the re-4 spectiverecesses 177, this swinging action bein produced by the pressure of therollers 157 against the lingers 149. As soon as the inner ends of thelevers enter t-he recesses 177 the heads 145 snap into engagement withthe heads of latches 146, this movement 0f the levers being acceleratedby the springs 148. The latches will thus hold levers 141 against thead`acent walls of the slots 142 and as the bloc 174 is advanced bylthefurther actions of the baler plunger, one end wall of each recess 177will come against the adjacent lever 141. As the levers are held ainstmovement about their pivots because o? their engagement by the latc es146, it will be obvious that as the block 174 continues' to advance, theend walls of the recess 177 will frame* member 46 therewith.Consequently this framemember, and all of the parts carriedthereby, willbe moved along the guideways and 43 in unisonwith the block 174. Theresistance to this movement offered by Athe weighted cables 169 will besufficient to shift the slide 80 within the recess 76 so that the gears`83` and 84 will be brought into mesh.

' A s the gears 82 and 83 are constantly rotatingthis action will resultin the rotation ofthe screw 71, causing thecross head 115 to feedtoward-the frame member 46 and the needles with their housings 121 toenter the cylindrical .portions 176 of the slots 175.

- Aftert'he free ends of the needles have passed transversely throughthe block 174, the levers 126 come against the spreading head 1131 so asto force the needles 130 longitudinally within the' housings 121 andmove the .'aws 137 away from the shoulders 140. See

igure 7. At the same time the deflecting finger 114 comes against thelever 112 1n ath thereof and actuates it to retract lt 106 from 'notch104. This immedilatel breaks the joint between the levers 103 so t atsaid levers can swing forwardly under the action ofthe weighted cablesagainst stops 179 supxported in the paths thereof.

These stops t us constitute fulcrums for le- `vers 103'so that they actto press backwardly through the slide1`00 a inst the slide 80,overcoming the action o the spring pressed most' position it will'thrustagainst the block 95, as `shown in'Figure 13, thereby imparting a .shortlongitudinal movement to the shifting bar 91. backwardly against theslides 100 and 80, they also thrustl the head 90 and the vpartsassociated therewith backwardly so'as to receive the'foot 92 of theshifting bar 91 between head 90 and the arm 86. In other words the head90v will be thrust back from the position shown in Figure 8 so as toextend across the foot 92 substantially as shown in Figure 11. Thus whenbar 91 is pulled longitudinally as alread will be shifted thereby to thepositions shown in Figures 11 and 12'. This produces two operations.First, the .ends of the cross head 87 come against the wings 150 of thelatches 146 so as to disengage said latches from the heads 145 of levers141. Second, the bolt 88 is withdrawn from the opening 101. Asv soon aslevers 141 are released from thelatches 146 the pulling action oftheweighted cables 169 will slide the frame member 46 and the partscarried thereby back tc their initial positions, lever 141 at thisy timedraggin along the adjacent side of the compresse material 152 andholding the rollers 15,7 and yoke 155 pressed laterally as shown inFigure 10. When' the bolt is withdrawn as explained the slide 100 willbe released so that the pulling action of the cables 169 on levers 103will result in the exertion of a backward pressure on slide 80 tomaintain the gears in neutral positions. They will hold these positionsas the block 162 on the depressed yoke 155 comes explained the head 90When the levers 103 thrust f member 46 so as to straighten out thelevers and cause them to lock as in Figure 9. Thus the parts are resetand the operation already described can be repeated. l

The mechanism thus far described constir anismswlll be correspondinglyincreased or.

engagement with the twisting mechanisms. One gear 67 is provided foreach of these y mechanisms so that when the shaft 62 and the partsdriven thereby are set in motion by the rotation of gear 69, both of themechanisms T will be operated simultaneously. Thus two tying actionswill occur at the same time where two sets of needles are used butobviously, where more or less than two sets of needles are usedthenumber of tyingmechreduced. As both tying mechanisms are the same adescription of one will suffice.

Carried by that portion of the frame 1 directly opposite the framemember 46 is a small table. 180 located between said frame and theadjacent side of the body structure 40. A guide sheave 181 is journaledon the outer portion of this table for the purpose of guidinga tie wireW, to the twisting mechanism. An arcuate blade 182 having a base 183 ismounted on the table close to the sheave 181 and is heldl adjust-ablyvin position by means of bolts 184`extending through slots 185. Thisblade is positioned to receive the free end portion of one 'of theneedles and its housing when said needleis at itsl extreme projectedposition. A groove'186 is formed' diagonally with the top Vface of thetable and extends from a point beneath the free' cut,- ting edge 187 ofthe blade 182. A recess 188 extends into the table under 'this cuttingedge 187 where it merges into onel end of the groove 186. The other endof the groove communicates with a depression 189 formed in the top ofthe table and a'bearing stud 190 projects from the table at `a pointbetween recess 188 and depression189. Depending from the table below theinner portion ofthe depression 189 is a hanger including apair ofchalineled guides 191.

Journaled in the lower end .portions of the lchanneled members 191- is ashaft 192 provided, at one end, with a gear 193. To

\ this same shaft is secured a cani 191 with which cooperates a pair ofoppositely disposed slides 195 and 196. The inner side of` the slide 195has a projecting lug 197 which overhangs a similar lug 198 formed on theinner side ofthe slide 196; Thus the slide `195 can move upwardlybetween the hangers independently of the slide 196 but should the slide196 be thrust upwardly by the cam 194 the projecting lug 198 would comeagainst lug 197 and cause both slidesto lift.. Springs 199 beardownwardly on the respective slides so as to hold them normally presseddownwardly on the lifting cam. 4Slide 196 .has a blade 200 fixedlyattached thereto and formed with a laterallyl extending tongue 201which, as

shown in Figure 17, is normally extended under the cars of the needlesand their housings. Mounted on therblade 200 at the upperl edge thereofand above the slide 196 is a guide sheave-` 202 for engagement by thetie wire lV.

vJournaled in the table .between one edge thereof'and the depression 189is a stem 2,03 provided at its outer end with a gear 20-1 and atits-inner end with a tapered head 205. This-stem has a longitudinalgroove 206 which extends through the gear 204E and the head 205, the'groove being of such depth as to extendinwardly slightly past the accessof rotation ofthe gear and the stem. T he groove in this stem normallyalines with the groove 186 in the table 180 and extending upwardly 1from the table at vone side of the grooved stem in a detlecting tongue207. A deiecting block 208is secured to the table at the other side ofthe stem 203 and this block cooperates with the tongue 207 to providea'wire receiving; throat of substantially the same width as the widthofthe groove 206. Thus when a wire is pressed downwardly between thetongue 207 and the block 208 it will be guided. accurately/into thegroove stem 203 so as to extend longitudinally thereof. AAnotherlongitudinally grooved stem 209 is'journaled inthe table at an acuteangle to thestem 20?. as shown particularly in Figure 17. This stern hasa gear 210 at its outer end and a tapered head -211 at its'inner end,this head, like the head 205, being extended into'the depression 189.The groove 212i`n the sten'r209 intersects gear 210 and head 211 and the`top ofthe table is slotted as at 213 to allow a tie wire to movedownwardly into the groove 212 when the stem 209 1s 1n its normalposition. An intermediate gear 211'is journaled cam 194`tlie rodv willalso be elevated so as to bring the finger 206' above the level ofthetable top. Likewise. when the slides are thus elevated theblade 200 willbe raised and the tongue 201 caused to pass a spring pressed latch 217slidablymountcd beneath the table. After the tongue 201 passes thelatch, said latchwill spring thereunder and support the slides and theparts connected thereto in their raised positions. A shaft 218 ismounted for rotation in the table and has a radial finger 219 whichengages the latch 217 so as to retract it against the action of thelatch spring 220. This shaft has a tripping Enger 221 above the table180, the finger being held by a. spring 222 normally in the path of oneof the needle housings. Y

A shaft 223 is journaled'in the table and is extended `at Iright angles,to the stem 209. Extending from that end of the shaft nearest l Thisfinger is adapted to work across 'the end of the head- 205.

in Figure 17. W hen thus located the fork will not interfere with theloweringl of a .tie

wire into the groove 186.

Secured to the finger 225 is a tripping block 228 adapted, duringtheforward swinging movement of the fork 226, to come againsta crank arm229 carried by a shaft 230 jour` naled on the table 180. Another arm 231is extended from the shaft 230 at an angle to the arm 229 and has alaterally extending d-ep pressing finger 232 adapted to swing downtheflange.

vcured to shaft 235.

wardly into ,the depression 189 when the arm 229 is swung upwardly -byblock 228. This depressing linger 232 is adapted to move downwardly toposition substantially atright angles to the groove 212 instem v209. v

Shaft 223 has agear 233 which meshes with a gear 234 secured to a shortshaft 235 journaled in the table. Another gear 236 is se- Journaled onthe stud y190 is a disk 237 provided. with a concentric gear 238 whichmeshes with one of the gears 67. vThis disk has a circumferential flange239 providing at opposite sides annular seats 240 and 241 respectively.This flange and the seats are intersected by a recess 242extending intothe periphery of the disk and/producing overhanging tongues 243 and 244at the ends of A One end of the. seat 241 is enlarged as at 245 to carrya bearingpin 246 on which is pivotally mounted' a dog 247 overhung bythe tongue 243. `A spring 248 bears against this dog and holds its freeend normally in engagementwith a star wheel 249 journaled as at 250 onthe inner side of the disk 237. This star wheel includes four teetharranged in pairs` the teeth 251 of one pair being oppositely disposedand equally spaced from the teeth 252 of the other pair. All of theteeth are suiciently broad to engage and lift the dog 247 but the outerends of the teeth l 251 are cut away at one side as shown at 253 whilethe outer ends of the other teeth 252 are cutaway as shownat 254.

For the purpose of actuating the star wheel a tripping pin 255 is'extended from the table 180 into the path of the wheel'. Mounted for-rotation in the seat 241 is a ring 256 having an annular seat 257 andprovidedon its face with a ring gear 258. This ring 'gear meshes withthe gear 204 so that duringone complete rotation of the ring gearseveral revolutions of the gears 204 and 210 will be produced.

That face of the ring 256 opposite the ring i.

gear has a short annular recess 259 one end of which terminates in ashoulder 260 while the other end is inclined as shown at 261.v See Fig.28. The depth of this recess 259 is sufficient to receive the adjacentsides of the teeth 252 at certain times during the operation of themechanism.` The annular seat 257 receives thev inwardly extended flange262 of an outer ring 263 lapping the periphery of the ring 256 and theflange 239. A retaining ring 264 is mounted for rotation on the seat24() and is fastened to the ring 263 so as to rotate therewith relativeto disk 237 and ring 256. This retaining ring has a portion of its innerperiphery cut away asshown at 265 so that during a portion of theoperation of the i mechanism the outer sides of the teeth'253 will befree to extend thereinto. This recess 265 is adapted, at a predeterminedtime during the rotation of the parts 264 and 263 to come to positionopposite an'inturned'head 266 provided at one end of an arm 267. Thisarm extends across the periphery of the ring 263 and is looped toprovide a dog 268 for engagement with the gear 258 ias shown in Figure29. A rod 269 is extended from this `dog and slidably mounted in thetable 180,

there being a spring 270 on the rod for holdling 4the dog 268-normallydisengaged-fromA the gear 258. Disengagement of these parts is preventedduring most of the rotation of ring 264 because the head 266 slidably.en,- gages said ring. When, however, the-recess 265 comes oppositehead'266, said head can be shifted theremto by spring 270 so as thus touncouple the dog 268 from the I'gear 258.4 A short peripheral gear 271is carried by the ,ring 263 and is adapted, on the completion of onehalf revolution of ring 263, to engage and rotate gear 193 of 1the cam194 while'. during the completion of the second halfof the revolution ofring 263 the peripheral gear 271 will engage and rotate gear 236 whichcontrols the actuation of the vlinger 235. The ring 263 has a forkedbracket 272 attached to the face thereof and this block is so locatedthat, during the rotation of ring 239-'the tie wire lying in the groove186 will be picked up by the forked block and folded back as hereinafterexplained. In practice `cutting edge 187 of blade182, longitudinallyabove the groove 186 and also longitudinally above the groove 206 in thestem 203. This wire W is extended transversely across'the body structur40 of the baling press. and the end thereof. is' gripped between the jaw137 and the shoulder o f one of the needles and its housing .as shown inFigure 40. At this time the needles, the frame member 46, the frame 47,andthe twisting mechanism are all in their initial positions as shownfor examplein Fi re `1. A The operation of the needles has a read beenexplained. A's the material being b ed is compressed within the bodystructure 40 it will force the said compressed material longitudinallywithin said structure and relative to the needles during which time thelevers 141 .will 4be held back as shown in Figure 10. Thus the relativepositions of the parts will gradually shift from those shown in Figure40 to those 'shown in Figure 41 atwhich time the kpull of the tie wireon the needle gripping the same will result in said needle shiftin fromthe position shown in Figure 40 to t e position/ shown in Figure 41.7This shiftin ofthe needles is permitted .in view of the act that thedisks 118 and4122 carrying the same'are rotatably mounted as shown inFigures 6 and 7. After the proper amount of material to form'a .bale hasbeen compressed a new dividing block, y which has been placed in themachine, comes to position .opposite the needles as shown in Figure 41whereupon the frame member 46 becomescoupled yto saidl block, theneedles armdirected transversely through the blocknlsee Figure42), thefree ends of the needles come to positions above` the table 180cooperating` therewith and the jaws 137 of the needles are thrust'toopen positions as shown in Figure 7. -At this time the needle whichcarries the wire W deposits the free end of said wire acrossthe groove4blade 182 so that t e space between the jaw 137 andthe shoulder 140will be located directly above that portion of the wire extendingbetween -,groove 186 andi sheave 181. These positionsof the parts havebeen shown in Figure 44; As soon as the needles reach ,these positionsso that'one of the'needles opens to release the end ofthe wireas inFigure 42 and the other opens above the wire adjacent the cutting blade,the needles be- ,gin 'to return to their. normal positions bytheoperation of the mechanism heretofore described. The closing of theneedle adjacent the cutting blade 182 will result in the gripping of thewire W thereby and just ras this wire is-gripped, the motion transmittedfrom gear`69 to the shaft 66 and gear 77 will-set in motion the tyingmechanism. The gears are `so proportioned that disk 137 will be giventwo revolutions by the time' the needles are completely retracted to thepositions shown by broken lines in. Figure 4. This retraction 'of theneedles' takes place gradually as the block 174 which is coupled to theframe member 46 travels from the position shown in Figure 1 Vto theposition shown in Figure 3. During the first revolution of this disk thedog 268 is in engagement with gear 258 so that said gear cannot rotate.,At the same .time one of the teeth 253 is projected into theV recess265 so that ring 264' is thus coupled to the disk 37. In-other words asthe disk r0- tates in the direction indicated by the arrow Y in Fi res28 and 35the projecting tooth 253 will t rust against one end wall ofrecess 265 at 265 (see Figure 28) and as the star wheel is held againstretrograde movement by the dog 247 it will be apparent that rotation of`the disk 237 andfring 64in` unison will be insured. As`\the ring 263 issecured to and ro tates with the ring 264 the rotation of these ringsby-gear 238 will result in movement of the forkedgbracket 272 so that itwill come up undcrthat portion of ther wire W adjacent the blade 182and` press the wire beyond the point where it has been gripped by one ofthe needles so as to shear said wire upon the edge or blade 182. As theforked block continues to rnove upwardly and laterally with y the ring263 it bendsthe severed-end ortion ofthe wire back upon itselfand over te previouslyreleased end of the wire-so as to form a hook as shown at273in Figure 45. As the wire is thus folded to form the hook it iscarried downwardly by the forked block 272 so as to press upon thefinger 216 and enter the groove 206. ImmediatelyV following this operationthe gear 27,1- engages gear 236 (see Figures 21 and 26) andimparts a partial rotation to said gear and to the gears 234' and 233.This rotation will be sufficient' to swing the finger 225 upwardly fromthe position shown in Figure 42 to the position s own in Figure 31.Consequently the fork 226 will enga e the vfree end of wire W thereaboveand old it forwardly and downwardlyiso as to position said end withinthe groove 212 in stem 209. In other words this end of the wire will bebent to form a hook 27 4engagingl the y' hook 273. See Figure 46..Following this operation, which occurs during-the completion of onerevolution of the rin 263 therecess 265fcomes opposite the hea 266 ofdog 268iand spring 270 pulls the do out of engagement with the gear 258.time one of the teeth of they star wheel 249 comes against the pin 255so that the wheel is rotating onev tooth 'and the tooth 251 isV shiftedinwardly out of engagement with reils cess265 while oneof the teeth 252is brought' to outwardly projecting osition after being snapped past thedog 24 Here this togth 252 will enter the'recess 259 in ring 256 withthe result that said ring will be coupled to the disk 237 and rotatetherewith during one revolution. As this .ring rotates within the ring263 which, with ring 264 is held by the downwardly and direct the wirehook 274 into the groove 212. `Consequently the simultaneous rotation ofthe two stems 203 and 209, will result in twisting the twofhooks so as`thus to produce intertting links as shown at 275 in Figure 47. On thecompletion of this rotation of gear 258 and ring 256 the star wheel 251will again be actuated by the .pin 255 so as to uncouple ring 256 fromthe disk 237 and couple the rings 264 and 263 to said disk. Consequentlthe ring 263-will again begin its rotation uring the first portion ofwhich gear 271 will engage and rotate gear 193 to actuate cam 194 'andthereby raise the slides 195 and 196 and subsequently release them. Thiswill cause the tongue 201 topress upwardly against those portions ofthewires projecting outwardly from the gears 204 and 210 so as to lift themout ofthe grooves 206 and 212. Consequently the tie is thus completedand will extend tightly around the fas ormed bale. While this operationhas been going onv the needles have been retracted from thev block 174coupled to the frame member 46 and the severed end portion of the wireon the `reel has beendrawn back to the position illustrated in Figure48. Thereafter, as eX- vplained in connection with the operation of vthe needlepmechanism, the frame member46 is brought back to the ositionshown in Figure 1, the sitions of t e needles are reversed as hereto oredescribed in connection with Figures40 and 41, another dividing block isplaced in position" and the operation already y described will berepeated. v

.It might be added that afterthe finger 225 "has been swung to theposition shown in Figure Bland the member 236 has moved out of mesh withgear 231, the spring 227 will return 'the arm 225 to its initialposition shown in Figure 42 and the fork 226', striking against 232 totheir initial positions .V

the 'arm 229, will restore the parts 231 and L When the blade 200withits tongue 201 lis vlifted to disengage the wires from the twistinggears, the finger 216 is also raised for the pur ose of lifting thenteriitting links out `of t e .heads 205 and 211.
